Organic reactants rapidly produce plastic foam [PDF]

open access: yes, 1965
Adding trichlorofluoromethane to polyether resin accelerates the reaction between the resin and toluene diisocyanate. This accelerated reaction instantaneously produces a plastic foam of low density and uniform porosity needed to provide buoyancy for ...

Reactions of N-acetylcysteine adducts of aromatic (di)isocyanates with functional groups of organic molecules [PDF]

open access: yes, 2008
Glutathione thiocarbamate conjugates of isocyanates play a key role in transport and final reactions of isocyanates in the human body by transcarbamoylation. N-acetylcysteine is the simplest model for thiocarbamate reactions.

Biocompatibility and cytotoxicity of two novel low-shrinkage dental resin matrices

open access: yesJournal of the Formosan Medical Association, 2014
To reduce the polymerization shrinkage of dental composite resin, we used two different ratios of toluene 2,4-diisocyanate (TDI) or 1,6-hexamethylene diisocyanate (HDI) as functional side chains of bisphenol A-glycidyl methacrylate (bis-GMA) to ...

An Adverse Outcome Pathway for Sensitization of the Respiratory Tract by Low-Molecular-Weight Chemicals: Building Evidence to Support the Utility of In Vitro and In Silico Methods in a Regulatory Context [PDF]

open access: yes, 2017
Sensitization of the respiratory tract is an important occupational health challenge, and understanding the mechanistic basis of this effect is necessary to support the development of toxicological tools to detect chemicals that may cause it. Here we use
